<span>The number of neutrons bromine will have are equal to
= protons + neutrons
so,

The correct answer is 3.4 moles of sulfuric acid (H₂SO₄) are needed to react completely with 6.8 moles of lithium hydroxide.
2LiOH + H₂SO₄ → Li₂SO₄ + 2H₂O
The given chemical equation is balanced.
By using stoichiometry, one can witness the following:
2 moles of LiOH requires 1 mole of H₂SO₄
So, 6.8 moles of LiOH requires (1/2) × 6.8 = 3.4 moles of H₂SO₄
The best example of immiscible liquids is
a polar liquid and a nonpolar liquid that do not dissolve into one another.
Explanation:
Immiscible averages that the fluids don't dissolve in each other – oil and water are an example. It is probable to swing up the juices and get them to mix but they soon separate. Departing immiscible liquids is done solely using a separating funnel.
<u>Answer:</u>
<em>The percentage error in the measurement is 2.4%
</em>
<u>Explanation:</u>
The measurement made by the student is
.
But the actual value of density is
The formula to calculate percentage error is
percentage error = 
Hence percentage error in this case is given by
<em>Percentage error =
</em>
<em>=
</em>
A physical quantities value will be determines by various quantities. If errors are made in measuring any of these quantities there will be error in the measurement of the final physical quantity as well.
Here density of a substance is a derived quantity determined by measuring mass and volume of that substance.<em> If errors are made in mass and volume measurements the density value will also be erroneous.
